Why Women Need Organ Meats: Hormones, Iron, and the Ancestral Approach to Women's Health

Nearly one in four Canadian women of childbearing age is iron deficient, and most of them don't know it. They chalk up the fatigue, the brain fog, the irregular cycles, and the feeling of running on empty to stress, bad sleep, or just being a modern woman with too much on her plate. But increasingly, researchers and clinicians are pointing to a simpler explanation: women are missing the nutrients their bodies were designed to run on, and no amount of green smoothies is going to close that gap.

The ancestral solution isn't complicated. For most of human history, organ meats, particularly liver, were considered the most prized foods a woman of childbearing age could eat. Rich in heme iron, retinol, B12, copper, and folate in their most bioavailable forms, organ meats delivered what the female body actually needs to regulate hormones, produce healthy blood, sustain energy, and support reproduction. Then we stopped eating them. And women started suffering for it in ways we've slowly normalized.

This post breaks down the nutritional science (and the ancestral logic) behind why organ meats for women deserve a serious second look.

The Iron Problem: Why Plant Iron Isn't Cutting It

Iron deficiency is the most common nutritional deficiency in women globally, and Canada is no exception. Statistics Canada data consistently shows that women aged 19 to 50 are chronically under-consuming iron relative to their needs, particularly those who are pregnant, postpartum, or experience heavy menstrual cycles.

Here's where the conventional advice goes wrong: it treats all iron equally. Dietary iron comes in two forms: heme iron (found in animal tissue, particularly organ meats) and non-heme iron (found in plants, fortified foods, and most supplements). The difference in absorption is staggering. Heme iron is absorbed at a rate of roughly 25–35%. Non-heme iron clocks in at 2–20%, and that absorption rate drops further in the presence of phytates, polyphenols, and calcium, which are ubiquitous in a plant-rich diet.

Grass-fed beef liver contains approximately 5 mg of highly absorbable heme iron per 100g serving. That's not a supplement dosage. That's food working the way food is supposed to work. Functional medicine practitioner Chris Kresser has written extensively on this, noting that liver is the most nutrient-dense food on earth and that its iron content is particularly relevant for menstruating women who are losing blood monthly and need consistent replenishment.

Symptoms of iron deficiency in women often include:

• Persistent fatigue that doesn't resolve with sleep
• Brain fog and difficulty concentrating
• Cold hands and feet
• Hair thinning and loss
• Restless legs and poor sleep quality
• Reduced exercise tolerance

Vitamin A and Hormonal Balance: Retinol vs. Beta-Carotene

Ask most nutritionists about Vitamin A and they'll point you to sweet potatoes or carrots. The problem is that the Vitamin A in plant foods is beta-carotene, a precursor that the body must convert into retinol (the active form) before it can be used. That conversion is notoriously inefficient: it takes anywhere from 12 to 21 units of beta-carotene to produce a single unit of retinol, and the conversion rate is further impaired by thyroid dysfunction, gut issues, and certain genetic variants, all more common in women than commonly acknowledged.

Retinol (true, preformed Vitamin A) is found almost exclusively in animal foods, and liver is the richest dietary source on earth. This matters enormously for women's hormonal health. Retinol plays a critical role in:

• Regulating estrogen and progesterone receptor sensitivity
• Supporting the synthesis of steroid hormones
• Maintaining healthy cervical mucus and reproductive tissue
• Reducing PMS symptoms and cycle irregularity
• Supporting skin integrity and reducing acne driven by hormonal imbalance

The Weston A. Price Foundation has documented traditional cultures around the world that specifically fed liver to women of reproductive age (often prioritizing it above muscle meat) precisely because of its role in fertility and reproductive health.

B12, Energy, and Fertility: The Nutrient Most Women Don't Get Enough Of

Vitamin B12 is essential for DNA synthesis, red blood cell production, neurological function, and (critically for women trying to conceive) proper methylation, the biochemical process that governs gene expression during early pregnancy. B12 deficiency is shockingly common, particularly in women who have reduced animal product intake, use oral contraceptives (which deplete B12 over time), or have impaired absorption due to digestive issues.

Beef liver contains approximately 70 micrograms of B12 per 100g, roughly 2,900% of the daily recommended value, in a form the body can use immediately. No conversion required. No absorption gamble. This is why traditional postpartum practices across cultures often centered on liver soups and organ-rich broths.

Copper and Thyroid Function: The Mineral Women Are Chronically Deficient In

Copper doesn't get the attention it deserves in women's health conversations, but it should. Copper is essential for thyroid hormone synthesis, iron metabolism (copper is required to mobilize iron from storage), collagen production, and immune regulation. Liver is among the richest dietary sources of bioavailable copper available, and provides it alongside the cofactors that allow the body to use copper correctly.

Subclinical hypothyroidism, which disproportionately affects women, is often discussed purely in terms of iodine or selenium, but copper deficiency is a frequently overlooked contributing factor. Women experiencing unexplained weight gain, cold sensitivity, fatigue, and hair loss may benefit from addressing copper status before escalating to pharmaceutical interventions.

Why Ancestral Women Ate Organ Meats First

Across virtually every traditional culture that hunted or raised animals, organ meats were not scraps. They were prizes. The liver, heart, and kidneys were consumed first, often by women of childbearing age, pregnant women, and children. Weston A. Price documented this across his travels to isolated populations in Switzerland, the Pacific Islands, Africa, and North America. Communities that maintained high organ meat consumption had robust fertility, healthy pregnancies, strong infants, and dramatically lower rates of the chronic diseases that plague modern women: irregular cycles, infertility, postpartum depression, hormonal acne, and early menopause.

The Case for Capsules

The nutrition case for organ meats is airtight. The practical case for eating liver three times a week is, for most women, considerably more complicated. This is where a high-quality organ supplement closes the gap without compromise. Rise Nutrition's Women's Formula is a grass-fed organ blend specifically formulated for women, combining liver, heart, kidney, and spleen in ratios designed to address the specific nutrient gaps most relevant to female physiology: heme iron, retinol, B12, copper, and CoQ10. No fillers. No synthetic vitamins. Just desiccated, freeze-dried organs from grass-fed cattle pasture-raised in New Zealand and Australia, in capsule form.

The Women's Formula is particularly well-suited for:

• Women experiencing fatigue and suspected iron deficiency
• Those with irregular or painful menstrual cycles
• Women trying to conceive or preparing for pregnancy
• Postpartum recovery
• Women coming off hormonal birth control
• Anyone who has been told their labs are "normal" but still feels exhausted and off

The Bottom Line

The fatigue, the brain fog, the irregular cycles: these aren't inevitable features of being a woman in 2025. In many cases, they're the predictable result of a nutritional gap that conventional medicine rarely addresses and standard supplements rarely fill.

If you're ready to give your body what it's actually asking for, Rise Nutrition's Women's Formula is the simplest place to start. Grass-fed, pasture-raised, formulated specifically for women.
